They would notice that the majority, if not all, of their depressive episodes, occur in the fall and winter months. Those with a spring-onset SAD may notice the opposite and experience decreased sleep, decreased appetite, and weight loss.
While there are several theories as to the cause of depression with a seasonal pattern, a quite common theory is that this fall-onset depression is caused by a decrease in natural daylight during the winter months. SAD appears to be more common among women, younger adults and those who live in Alaska, Canada, and U.S. northern border states (because of high latitude).
Intuitively, since they know when it is coming, lots of people adapt and find themselves making behavioral changes to handle their depression.
By doing things like ensuring they are achieving adequate sleep, leaning into their support system, following a healthier diet, and increasing exercise they are taking part in activities that can help a mild to moderate low mood significantly.
For those who need more than these behavioral modifications, treatment generally consists of three components:
- Light therapy – Light therapy includes spending time in front of bright lamps during the day, mostly in the early morning hours. This should be done under the instruction of a physician since there are specific recommendations about the amount of lux (light intensity measurement) required to be effective and because there are some medical conditions and medications that require closer monitoring of use. While this has been shown to be effective, some people do not like it due to the inconvenience of having to use the light in the morning when they are often busy getting ready for the day.
- Antidepressants – Treatment with antidepressants has been found to help people with depression, including those with a seasonal component. There are several options available but everyone with depression doesn’t necessarily need an antidepressant. The antidepressant can be taken year around or can be stopped in spring and restarted annually in the fall/winter months (or vice versa for the spring-onset variant). Whether you will use an antidepressant and on what schedule will depend upon the severity of your symptoms and your preferences.
- Psychotherapy – Psychotherapy, also known as talk therapy or counseling, is an effective treatment option for any kind of depressive episode and one that I strongly recommend to anyone with depression.
If you are someone who finds it difficult to function as well during the winter months and struggles with getting out of bed for work, socializing, focusing on work, weight gain or lower mood this time of year, you just may be dealing with Seasonal Affective Disorder and should strongly consider talking to your doctor about what can be done.
